T. cLEMENsoN KILLER FYQR GREASE GUNS Filed Sept.` 14, 1935 figa/Lahe Kleine/son Patented Aug. 11, 1936 l UNITED STATESv PATENT OFFICE 1 Claim.

This invention aims to provide a novel device for holding grease and the like, of the kind usually employed in connection with grease guns. The invention aims to provide novel means whereby the grease may be forced out of the receptacle, into a grease gun, it being possible to eject practically all of the grease, and there being little or none of the grease left in the receptacle. The invention aims to provide novel means for constructing and reenforcing the lower end of the receptacle. A further object of the invention is to provide a device of the class described so constructed that one of them may be stacked readily on top of another, without danger of having the superposed receptacle slip laterally or fall down.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being un-i derstood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawing:

Fig. l shows in longitudinal section, a device constructed in accordance with the invention, parts being in elevation;

Fig. 2 is a top plan;

Fig. 3 is a transverse section on the line 3-3 of Fig. l;

Fig. 4 is a section on the line 4--4 of Fig. 3.

The device forming the Subject matter of this application comprises a receptacle, made of any suitable material, preferably sheet metal. The receptacle embodies a tubular or cylindrical body I, provided adjacent to its lower end with an inwardly projecting, annular, horizontal shoulder 2, terminating in a depending tubular neck 3, of less diameter than the body I. Within the bodyv I, and secured in place, is a bottom 4. The constituent material of the bottom 4 preferably is somewhat thicker than the material out of which the body I is made. The bottom 4 has a depending annular flange 5, fitting closely within the smooth lower portion of the body I. At its' lower edge, the flange. 5 is suppliedwith an inwardly projecting annular shoulder 6, resting on the shoulder 2 of the body I. The shoulder 6 is supplied with a depending neck 1, fitting closely within the neck 3 ofthe body I. The bottom 4 is provided with a depressed trough 8, extending from a point near to the center of the bottom, to the periphery of the bottom. The inner end nf the trough 8 may be inclined, as shown at I6. 'I'he body 2 is supplied with an opening 9, located 5 at the outer end of the trough 8, and communicating therewith. A horizontal spout I0, or any other kind of a spout, is secured to the outer surface of the body I, about the opening 9 in the body.

The body I is corrugated to form a continuous and spiral thread I I, extending downwardly from the extreme upper edge of the body to the bottom 4. The numeral I2 designates a disk-like top, having an upstanding annular rim I4, which is l5 engaged with the spiral thread il of the body I. A transverse handle I5 is secured to the top I2.

In practical operation, the body I is lled with grease or any other lubricant, indicated at I1,

and the top I2 is threaded into the body I, as 20 shown in Fig. 1. When the occasion for the use of the device arises, the top I2 is threaded downwardly in the body I, and the grease, led by the trough 8, passes through the opening 9 of the body, into the spout I0, and from the spout into 25 the grease gun to-be filled. The top I2 may be threaded downwardly until the top rests on the bottom 4, and practically all of the grease in the receptacle can be forced out.

The parts 1, 3, 5, 6 and 2 reenforce the recep- 30 tacle at its bottom, and give an unusually strong construction.

The external diameter of the tubular neck 3 of the body I is slightly less, or approximately equal to, the internal diameter of the upstanding rim I4 of the top I2. Consequently, the neck 3 of one receptacle may be placedwithin the rim I4 of another receptacle, and in this way, the devices may be stacked up to any reasonable height, `without danger that they will slip laterally on each other and fall down.

The device forming the subject matter of this application is simplein construction, but will be found thoroughly effective for the ends in view.

Having thus described the invention, what is 45 claimed is:

In a device of the class described, a receptacle including a tubular body provided with an outlet, a bottom in the body and having a depressed` trough leading to the outlet, the body having a continuous thread leading from the extreme upper edge of the body to the bottom, a top having a plain, ilat lower surface shaped to t against the entire upper surface of the bottom saving where the trough exists, the top having an up- 65 standing rim which is engaged throughout its entire height with the thread when the upper edge of the rim is iiush with the upper edge oi the body 'and when the top is engaged with the bottom, an upstanding handle on the top, the body having a reduced neck at its lower end, the neck being receivable within the rim of the top ot a like receptacle, to facilitate stacking, the height of the neck being at least equal to the height of the handle, to avoid contact between the handle of a lower receptacle` and the trough ot an upper receptacle, thereby to avoid consequent instability in stacking.
